Application led March 19, 1914. Serial No. 825,877.

To all whom t may concern:

Be it known that we, EDWARD H. KRAUTI-I and En HAMBLIN, J r., citizens of the United States, residing at Woodward, in the county of Woodward and State of Oklahoma, have invented a new and useful Combination Carpenter-Tool, of which the following is a specification.

One object of the present invention is to provide a floor jack having novel means for gripping a floor timber.

It is within the scope of the invention to improve generally and to enhance the utility of devices of that type to which the present invention appertains.

With the above and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of partsand in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

ln the accompanying drawing: Figure 1 is a perspective View depicting the floor jack forming the subject matter of this application; Fig. 2 is a perspective showing the primary grip portion of the floor jack; Fig. 3 is a perspective showing an extension attachment which is assembled with the structure shown in Fig. 2; Fig. 4 is a perspective illustrating one of the elements whereby one of the portions of the floor jack is assembled with the bar or handle. Fig. 5 is a sectional detail illustrating the pivotal connection between certain parts of the structure.

The floor jack herein disclosed includes aprimary grip which is denoted generally by the numeral 37, the grip 37 including a barlike body 38 provided in one face with a longitudinal groove 39. In the bar 38, openings 40 are formed. The bar 38 is provided adjacent one end with transverse grooves 41 and 42.

The primary grip includes an extension 43, in the form of a bar, the same being provided with transverse ingers 44 and 45. rl'he bar 43 is adapted to lie partly in the groove 39, the fingers 45 registering in the notches 42 and the fingers 44 registering in the notches 41. A securing element 46 which may be a screw, may be lodged in either of the openings 40 in the bar 38, and

is adapted to engage in an opening 47 formed in the extension 43. l/Vhen the securing element 4G is mounted in the opening 40 which is nearest to the end of the bar'33, then the lingers 44 on the bar 43 register in the notches 42. In this manner, the effective length of the primary grip 37 may be lengtln cned or shortened at will in that the bar 43 may be disposed in two different positions longitudinally of the part 3S. At its lower end, the extension 43 terminates in a hook 48 or other holding element, adapted to a like end, the function of the part 43 being set forth hereinafter. Projecting rearwardly from the bar 33 is a stud 49, provided with an intermediate shoulder 50. The stud 49 is rotatably received in an opening in a bar 1, and in this manner, the primary grip 37 is connected with the bar for pivotal movement, the parts in question being held together by means of a pin 51 inserted through the stud 49 in back of the bar l. The shoulder on the stud 49 serves to space the bar 3S apart from the element 1.

The invention further includes a secondary grip denoted generally by the numeral 52. The secondary grip 52 comprises a body 53 and laterally extended arms 54 and 55, the body including a` stem 56, located in alinement with the bodv 53, the stem 56 terminating in a prong 57. A, pivot element 53, mounted .in the upper end of the bar 33, passes through. the stem 56 and affords a pivotal connection between the primary grip 37 and the secondary grip 52, the parts being held together for pivotal movement by means of the cotter pin 59 inserted into the pivot element 53. In the body portion there is formed a longitudinal slot 7l communicating with a transverse slot, the latter comprising part-s 73 and 72, located respectively in the arms and 54, and in alinement. ln the arm 55 there are transverse openings 60, and similar openings 61 are formed in the arni 54. Into either pair of these openings may be inserted a key 62, the same preferably being in the form of a pin. The pin or key 62 may be retained within convenient reach of the operator by means of a chain 63, so that the pin or key may be inserted into either of the pairs of openings or 61. A pivot element, preferably in the form of a bolt 64 is threaded into an opening in the bar 1. Mounted upon the bolt 64 is a nut 65 which engages one side of the bar 1 and serves to space the secondary grip 52 there from. The bolt 64, beyond the nut 65, is adapted to move in the slot 71-72-73, and in order to secure the secondary grip 52 upon the bolt 64, the latter is provided with a transverse head 66 which is of unequal transverse dimensions, the head 66 being effective to hold the secondary grip in place, but the bolt 64 being capable of manipulation, so that when the longer dimension of the yhead 66 extends longitudinally of the slot 71, the secondary grip may be removed. A pivot element 67 is mounted in the bar 1 and upon the pivot element 67 is movably supported a brace 68.

Presupposin'g that the structure is to be employed for pressing up flooring, the floor timber may be taken to be shown at 75, one ol the floor boards being indicated at 69. The extension 43 being properly positioned on the bar 3S in the manner hereinbefore described, the hook 48 is engaged with the lower edge of the floor timber 75. Then the bar 1 is swung over in the direction of the arrow A. The bolt 64 will thereupon ride in the slot 71 and the secondary grip 52 will be tilted upon its fulcrum 58, the prong 57 biting into the upper edge of the floor timber 75. Ultimately, the bolt 64 will arrive at the point of juncture between the slotsr 71 and 72. Then, as the bar 1 is swung still farther in the direction of the arrow A and as one edge oit' the bar 1 is brought into contact with the Hoor board 69, to hold the same in place, the bolt 64 will travel in the direction of the arrow C and move toward the end of the slot 72. When the floor board 69 has been crowded up suficiently by the action of the lever or handle 1, the brace 68 is dropped and the bar 1 is held in clamping position with respect to the board 69'while the latter is nailed down onto the floor timber 75.

During the operation'above described, the key or pin 62 is removed from the openings 61 in the arm 54 but, after the Hoor board 69 has been nailed down, the pin or key 62 is dropped into the openings 61 as shown in Figfl. Then, if the handle or lever 1 be swung in a direction opposite to that indicated bv the reference character A, the bolt 64 which now lies adjacent the end of the slot 72 will strike the pin or key 62 and effect a release of the prong 57 from the floor timber 75.

It is to be noted that the arm 55 is pro vided with a slot 73 and that openings 60 Copies of this patent Ymay be obtained for are fashioned in the arm 55. Owing to this construction, the device may be operated either by a right handed person, or a left handed person, the operation being the same in either case, saving for the fact that the brace 68 extends in an opposite direction from that shown in the drawings, that the bar 1 during the clamping action is swung in a direction opposite to that indicated by the reference arrow A, and that the stud 64 moves into the slot 73 of the arm 55, instead of operating in the slot 72 of the arm 54, the key 62, of course, being inserted into the openings in the arm Having thus described the invention, what is claimed is 1. A floor jack comprising a handle; ay primary grip pivoted to the handle; a secondary grip pivoted to the primary grip and including` a longitudinal slot having a transverse extension; a securing element on the handle and located in the longitudinalslot, the securing element being adapted to traverse the longitudinal slot and enter the eX- tension; and aI key removably mounted in the secondary grip and protruding into the extension. A

2. A floor jack comprising a handle; a primary grip pivoted to the handle: a sccondary grip pivoted intermediate its ends to the primary grip and including a longitudinal slot having a transverse extension', a securing element on the handle and located in the longitudinal slot, the securing element being adapted to traverse the longitudinal slot and enter the extension.

3. In a Hoor jack, a door compressing handle; a primary grip pivoted intermediate its ends to the handle and provided adjacent its lower end with a lateral. bcam-en A gaging projection; a secondary grip pivoted intermediate its ends to the upper end of the primary grip, the lower end of the secondary grip constituting a beam-engaging element; and means for slidablv and pivot` ally connecting the upper end of the secondary grip with the handle.

In testimony that we claim the foregoing as our own, we have hereto afixed our sig natures in the presence of two witnesses.
